18. spite its small size the VT1000 Valve Tester is a highly accurate and sensitive piece of test equipment and should be treated as such When in use the VT1000 is taking thousands of micro measurements and performing over 20 tests in order to grade your valves These tests measure very small voltage and current changes under high impedance conditions which means a number of external factors can affect the end results To obtain the most consistent readings we advise observing the following 1 The Valve Tester casing is made from thick heavy duty metal During transit storage they are enclosed in their boxes and can be subject to various changes in temperature and humidity Any condensation which may occur on the valve bases or internally can influence initial results Due to the thermal insulation properties of the packaging and the high thermal mass of the metal case the VT1000 may remain at a very low temperature for a considerable time if left in the packaging If it is brought into a warm room and immediately used condensation will naturally occur and produce false test readings For this reason it is recommended the VT1000 is allowed to stand for around 30 minutes out of its packaging before initial use for these effects to subside 2 With temperature being a factor we suggest that the VT1000 is used wherever practically possible in a location where temperature and humidity will remain constant If inconsistent test results are being obs
